| ［摘要］ 目的 分析孕前及孕中晚期孕妇体重增加对新生儿出生体重的影响。方法 前瞻性选取2016年10月至2020年10月在山东省滕州市妇幼保健院围产期建卡常规产检并分娩的1 820例孕产妇，收集人口学特征、产检信息、妊娠结局等资料，采用二分类logistic回归模型分析孕前体质量指数（BMI）及孕中晚期孕妇体重增加与新生儿出生体重的相关性。结果 孕前低体重（OR=6.089，95%CI：4.075～9.099）是低体重儿发生的危险因素；孕前超重（OR=5.799，95%CI：3.895～8.636）及肥胖（OR=11.779，95%CI：7.096～19.554）是巨大儿发生的危险因素。孕中期（OR=6.261，95%CI：3.854～10.170）、孕晚期（OR=6.926，95%CI：4.495～10.672）增重低于医学研究院（IOM）标准是低体重儿发生的危险因素；孕中期（OR=1.496，95%CI：1.059～2.113）、孕晚期（OR=1.812，95%CI：1.279～2.567）增重超IOM标准是巨大儿发生的危险因素。结论 孕前BMI与孕中晚期体重增加速度对胎儿发育的影响较大，临床应根据孕妇身体素质在特定阶段给予针对性干预，以确保孕期体重增加的合理性，进一步促进妊娠结局的改善。 |

| ［Abstract］ Objective To analyze the effects of the weight gain of pregnant women before pregnancy and in the second and third trimesters of pregnancy on neonatal birth weight. Methods A total of 1 820 pregnant women who were created medical files for giving birth and underwent routine perinatal examinations and gave birth at Tengzhou Maternal and Child Health Hospital, Shandong Province from October 2016 to October 2020 were prospectively selected. The data on basic demographic characteristics, antenatal information and pregnancy outcomes were collected. The binary logistic regression model was used to analyze the correlation between the pre-pregnancy body mass index(BMI) and the weight gain of pregnant women in the second and third trimesters of pregnancy and the birth weight of newborns. Results The low weight of pregnant women before pregnancy(OR=6.089, 95%CI: 4.075-9.099) was the risk factor of low weight infants. Overweight(OR=5.799, 95%CI: 3.895-8.636) and obesity(OR=11.779, 95%CI: 7.096-19.554) of pregnant women before pregnancy were the risk factors of macrosomia. The low Institute of Medicine(IOM) criteria of weight gain in the second trimester(OR=6.261, 95%CI: 3.854-10.170) and the third trimester(OR=6.926, 95%CI: 4.495-10.672) of pregnancy were the risk factors for the occurrence of low weight infants. The excess IOM criteria of weight gain in the second trimester(OR=1.496, 95%CI: 1.059-2.113) and the third trimester(OR=1.812, 95%CI: 1.279-2.567) of pregnancy were the risk factors for the occurrence of macrosomia. Conclusion The pre-pregnancy BMI and the rates of weight gain in the second and third trimesters have a greater impact on fetal development. Clinical targeted interventions should be given to pregnant women at specific stages according to their physical fitness to ensure the reasonable weight gain during pregnancy and further improve pregnancy outcomes. |
